PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Tap once. A random color fills the screen — named, coded, and ready to copy as HEX, RGB, or HSL. ColorRandom is a random color generator for people who need a color right now: no boards, no sign-up screens between you and the color, just a fresh specimen on every tap and a one-tap copy of its code. Most random color apps roll the dice the same way every time. ColorRandom gives you eight documented sampling modes — and tells you exactly how each one works. Pastel, Vivid, Muted, Deep, Warm, and Cool sample specific regions of color space; Spread steps the hue by the golden ratio so consecutive colors stay far apart; Any is uniform over the whole RGB cube. Every color is also named perceptually in CIELAB, so the label you read matches what the rest of the world calls that color. WHAT YOU GET • A full-screen color on every tap, with its everyday name — Cobalt Blue, Peach, Sea Green — matched by perceptual distance, not guesswork • HEX, RGB, and HSL side by side, each copied to your clipboard in a single tap • Eight sampling modes, from soft pastels to deep near-blacks, including a golden-ratio Spread mode that keeps back-to-back colors from looking alike • A WCAG 2.1 contrast readout under every color: the exact ratio against white and against black, graded AA or AAA before you put text on it • A bookmark archive of the colors worth keeping — tap any saved specimen to bring it back full screen • Palette export as a hex list, CSS variables, ready-to-paste SwiftUI code, JSON, or a printable PNG sheet PERFECT FOR • Developers who need a color code in the next ten seconds, not a design meeting • Designers shaking off a stale mood board with genuinely random inspiration • Students seeing how hue, saturation, and lightness map onto hex and RGB values • Anyone who color-codes calendars, spreadsheets, teams, or cables and is tired of choosing WHY NOT JUST A PALETTE WEBSITE? Palette sites hand you five-color schemes someone else curated, behind a browser tab and a login prompt. ColorRandom gives you one honest random color at a time, with its codes and its contrast math, entirely on your phone. When surprise is the point, curation is the enemy. PRIVATE BY DEFAULT Everything runs on your iPhone. No account, no tracking, no analytics on your taps. Your saved colors are stored on-device and never leave it. PREMIUM (PURCHASE REQUIRED) ColorRandom Pro unlocks the unlimited color archive and every export format — hex list, CSS, SwiftUI, JSON, and the PNG palette sheet. Choose the weekly or yearly subscription, or make a one-time lifetime purchase. Tap the swatch. The next color is already waiting.
